NEW NEUTRON DETECTOR BY FISSION IN A FLOWING GAS (in French)

Journal Article · · J. Nuclear Energy
With the Instruments and methods described in this paper it is possible to measure, at any time, a flux of slow neutrons in presence of very intense fluxes of gamma -rays: fission products are carried by a gas stream past a BETA -, gamma counter. The minimum measurable flux is of the order of a few thermal neutrons per cm/sup 2/ and per second. The power of a nuclear reactor can be easiIy followed; neutron density maps can be plotted very accurately as soon as fluxes are greater than 10/sup 8//cm/s. Temperature resistance is excellent.
